Full one-fluid dusty gas with multiple grain species in SPH
Mark Hutchison, Guillaume Laibe, Giovanni Tedeschi-Prades +5
We present a Smoothed Particle Hydrodynamics (SPH) implementation of the full one-fluid dusty gas algorithm for multiple dust species, generalising our previous terminal velocity a…
Modelling dust coagulation, dynamical drag and turbulent mixing during star and disc formation
Matthew R. Bate, Mark A. Hutchison, Daniel Elsender
Planet formation in the discs around young stars involves the coagulation of sub-micron sized dust grains into much larger grains that may be mixed by turbulence and migrate throug…
General Implicit Runge-Kutta Integrators for Multifluid Gas-Dust Aerodynamic Drag
Giovanni Tedeschi-Prades, Til Birnstiel, Klaus Dolag +2
The integration of aerodynamic drag is a fundamental step in simulating dust dynamics in hydrodynamical simulations. We propose a novel integration scheme, designed to be compatibl…
Modeling dust dynamics in OpenGadget3 -- I. SPH implementation of the One-Fluid model
Giovanni Tedeschi-Prades, Til Birnstiel, Klaus Dolag +2
Dust dynamics plays a critical role in astrophysical processes and has been modeled in hydrodynamical simulations using various approaches. Among particle-based methods like Smooth…
